Recent forecasts from Environment Canada and other models show Toronto's overnight minimum on September 12 clustering near 12–13°C, driven by clear to partly cloudy skies, light winds, and dew points supporting radiative cooling after daytime highs around 26°C. Current observations near 13–14°C at dawn align with this range, while historical September 12 averages of 14.5°C provide context for the slightly cooler outlook. Model consensus and the absence of strong warm-air advection or cloud cover keep 13°C as the market leader at 62% implied probability, with 12°C close behind; any shift in steering patterns or precipitation timing could adjust these odds before final readings.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=cyyz
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
